Blender has very few function compare to the other programs ,like I am comparing GIMP to Photoshop.
No doubt Photoshop is better than GIMP a lot but it comes with the prices of long startup and memory task.
GIMP has few functions but I dare say that it has every functions that need to exists, this is also applied to Blender.
Blender is very fast at startup and operating ,unlike 3d Max or Maya, it tooks minute to start up but this may had been improved because I did not use them for almost 20 years.
